MG Intumescent Grille (Slotted)
- Product SKU: Product 35 -MGslot- 0
- Category: Ventilation
Intumescent ventilation grilles consisting of two metal plates which hold intumescent material fitted onto either side of a door or wall. The grille has ventilation slots to improve airflow quality. The intumescent material contained within the grille will expand in under a minute to seal the openings preventing the spread of fire and smoke.
The grilles are suitable for operational theatres, sterile areas, and food preparation spaces providing an effective fire protection solution. Once the grille reaches 70℃ the link breaks and the inner intumescent plate drops, sealing the grille. Fires will then become compartmentalised preventing the spread of flame and smoke. Furthermore, allowing for the preservation of building structures (important for listed buildings) and safe time for occupants to escape
Tested to the BS476 parts 20 and 22 (1987), achieving 66 minutes integrity on one side only; and BS476 part 22 (1987) achieving 73 minutes integrity. Also tested to EN1363-1 (2000).
Specifically designed passive fire protection range to meet Document B of Building Regulations as well as being tested to the European Standards. Browse our full range of ventilation products online for more information
–Utilises either side of the ventilation opening in fire rated doors and walls to provide up to 73 minutes integrity
–Available in two forms to suit situations where only one or both sides of the wall or door are at risk.
The sets are defined in two ways: the /D version is for use in situations in which the risk is double sided (that is, the opening could be attacked from either side by fire); and the /S version is for the use in situations which it has been clearly identified that only a single side of the opening is at risk. When fitting the /S version the intumescent plate is placed on the risk side, and the plain plate is placed on the opposite side of the opening. Order the grilles to suit the opening that needs protected - the external size of the grilles has to be at least 50mm larger than the opening to allow for fixing. Special sizes can be made (prices quoted on request).
